摘要: 目的 建立测定硫酸阿托品滴眼液中硫酸阿托品含量的方法。方法 采用Alhech-C18(5μm 4.6×250mm)色谱柱固定相,以乙腈-0.05mol/L庚烷磺酸钠水溶液(35:65)为流动相,检测波长210nm。结果 硫酸阿托品在8-120μg/mL浓度范围内线性良好,线性回归方程为:A=-72915.4073+15308.1639C,r=0.999,平均回收率为100.2%,RSD=0.65%。结论 本法操作简单,快速,准确可靠,回收率高。Abstract: Objective An ion-pair HPLC method was developed for determination of atropine sulfate in atropine sulfate eye drops. Methods Alltech-C18 (4.6×250mm, 5μm)column was used and the mobile phase was acetonitrile -0.05mol/L sodium hep-tanesul fonate (35:65). It was detected at 210nm. ResultsLinearity was obtained in the concentration rage of 8-120μg/mL, A=-72915.4073 + 15308.1639C,r=0.999. The average recoveries was 100.2%, RSD = 0.65%. Conclusion The method provide a accurate and sensitive way for the determination of atropine sulfate in atropine sulfate eye drops by ion-pair HPLC.
